Neutron resonances in three-body system in the thermal range

Abstract

The main objective of the work is to determine the new resonances in three-body system that consists of one neutron and two heavy nuclei. New resonances are formed in the re-scattering of neutron on subsystem of these nuclei. Such neutron resonances become stronger at particular values of the distances between the nuclei and the resonances vanish if distances become larger or less than these resonance distances. Theoretical analysis of the properties of new resonances in three-body systems are given and calculations of the resonance characteristics are provided. Possibilities for experimental studies of new resonance effects are discussed. It is suggested to investigate new neutron resonances in piezo-crystals that contain isotopes, which have resonances in the thermal range. As the sample the isotopes of 113 Cd are considered because the corresponding the electric piezoeffect allows to vary the distances between the nuclei.
